PLOW.

Specification of Letters Patent.

Patented Dec. 15, 1914.

Application filed June 4, 1914. Serial No. 842,856.

To all whom it may concern:

,Be it known that I, J OHN F. SHEAHAN, a citizen of the United States, residing at Canton, in the county of Fulton and State of Illinois, have invented new and useful Improvements in Plows, of which the following is a specification.

The invention relates to plows and more particularly to means for securing the share bination of parts as hereinafter set forth and pointed out in-the appended claims.

In the accompanying drawings; Figure 1 is an inverted plan view of the plow body.

Fig. 2 is a similar view showing the share disconnected. Fig. 3 is a detail section on the line 33 of F 1 takenin the direction of the arrows as shown. Fig. 4 is a detail section taken on the line 41 of Fig. 3. Fig. 5 is a section on the hue 5-5 of Fig. 1 taken in the direction of the arrows as shown, and Fig. 6 is a detail perspective a view.

The invention will be best understood from a consideration ofthe following detailed description, taken in connection'with the accompan ing drawings forming a part of this speci cation, with the further understanding that while the drawings show a partial form of the invention, the latter is not confined to any strict conformity with the showing of the drawings, but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention.

Like and corresponding parts are indicated by similar reference characters throughout the several views.

The mold-board indicated by the numeral 1 is connected to the frog 2 by means of bolts 3 and 4: respectively in the usual manner. The landside bar 5 is also rigidly connected to the frog 2 by means of bolts 6. The share 7 is provided with. a landside flange 8 and is adapted to be connected to the mold-board and frog.

The foregoing parts and connections as named are within the art and further detail description is thought unnecessary.

As stated in the beginning of the specification, the invention seeks to provide a quick detachable connection between the share and the remaining parts of the plow body. This connection comprises a brace 9 having its lower arm rigidly connected to the frog by means of the bolt 4, and its upper arm rigidly connected to the mold board by means of the bolt 10.

A bolt'll is carried by the heel portion of the share and is provided with a washer 12 and'nut 13. This bolt is arranged to engage a notch 14, formed in one end of the upper arm of the brace. When the share 15 in position its heel will be securely held in place by tightening the nut 13.

The brace 9 is provided with an apertured lug 15 through which extends a bolt 16 having one end threaded upon which is a nut 17, and the opposite end of the bolt is flattened and offset as at 18. The flattened end 18 of the bolt is slotted, having an enlarged portion 19 being slightly larger than the head of a bolt 20 secured to the? share whereby the end 18 of the bolt may be easily placed over the head of the bolt 20 and the reduced portion of the slot receive the shank portion of the bolt 20.

The offset portion of the bolt 16 rides upon the beveled edge 21 of the upper portion of the frog when tightening the nut 17, which will pull the heel of the share against the edge of the mold board and the upper face of the frog thereby forminga tight and smooth connection.

The rear end of flange 8 abuts against the forward end of the landside bar 5 and the toe end of the frog projects over the rear end of the flange. The landside face of the toe end of the frog is cut away as at 22, and interposed between the toe end of the frog and shaft flange is a locking plate 23. This locking plate is provided with a projecting stud 24 which is adapted to rest within an opening 25 formed within the shaft flange 8 whereby a pivoted connection between the locking plate and flange is provided. The upper edge 26 of the locking plate has substantially the same configuration as the inner face of the shaft, but is spaced therefrom as better shown in Figs. 3 and 4, and the outer edge of the plate is provided with a flange 27.

The landside flange 28 of the toe end of the frog is tapered and by forcing this tapered end of the frog upon the locking plate between the flange 27 and the share 7 a wedging action takes place, thereby rigidly locking the toe end of the share to the frog. By having the lockin plate pivotally mounted upon the share ange 8 it will permit the frog to be readily placed into position and will take up any irregularities in the toe end of the frog due to imperfections in the manufacture of same.

The share may be readily removed by loosening the nuts 13 and 17 and moving the bolt 16 forward so that the portion 19 of the slot is in alinement with the head of the bolt 20,.whereby the bolt 16- can be disconnected from the share by pulling out upon the forward end of the bolt. Then by moving the share longitudinally it will be separated from the other parts of the plow body, as indicated in Fig. 2.

The improved construction serves to rigidly hold the share in position while permitting a quick detachable connection.

I claim as my invention 1. The combination with a plow, a removable share having a landside flange, of a removable locking plate carried by said flange and the frog of the plow adapted to be engaged by said plate for locking the share to the frog.

2. The combination with a plow having a moldboard and a removable share, of a detachable plate pivotally mounted upon the share for locking the same to the moldboard substantially as described.

.3. In a plow body, a frog having a tapered toe, a share having a landside flange, means detachably mounted upon the landside flange for locking said tapered toe between the share and the landside flange.

4. The combination with a plow having a moldboard, a frog and a removable share having a landside flange, of a plate resting upon one face of the landside flange, and the frog being adapted to be engaged by said plate for locking the share thereto.

5. The combination of a plow, a share having a landside flange, of a plate mounted upon said flange, a frog provided with a toe portion adaptedto rest upon said plate, means for locking the share to the plow body whereby said toe portion will be wedged between the plate and share for the purpose specified.

6. .In a plow body, a frog .having longitudinally extending shoulders on its landside and main portion at its forward end, a share having a landside flange, a pivotally mounted plate carried by the landside flange, said shoulders being adapted to rest between the share and said plate for the purpose specified.
